ENGLEWOOD, Colo. â?? As far as Peyton Manning is concerned, the offseason party line that the Denver Broncos would use their playoff loss to the Baltimore Ravens as motivation for 2013 is history.

Manning, in his first news conference of the regular season Sunday, shook off multiple questions about Denver's 38-35 double-overtime playoff loss to the Ravens in advance of Thursday's rematch at Sports Authority Field at Mile High.

"This is a new season for us," Manning said. "We're playing a new team."

He was testy with the out-of-town media, too, telling the Ravens beat reporters on a teleconference: "I covered that just about all offseason. I know I'm talking to you guys for the first time, but I guess you just have to probably check some old clips for quotes.''

Part of the Broncos' preparation has included watching Denver's two games against Baltimore from last season â?? a regular-season win in Baltimore and the playoff loss on a frigid January evening in Denver â?? but Manning was in no mood to rehash either game.

This is vintage regular-season Manning. The affable offseason quarterback -- who would publicly poke fun at his silly television commercials or crack jokes on his teammates -- has gone back into hibernation.

This version of Manning is now focused on the Baltimore defensem which, despite losing linebackers Ray Lewis, Dannell Ellerbe and Paul Kruger, has a healthy No. 1 cornerback in Lardarius Webb and a new pass rusher who looks quite familiar â?? Elvis Dumervil, who spent the past seven years with the Broncos.

"They've replaced some really good players with another round of good players, brought in some experience, some athleticism. Until you've played them, you probably don't know them as well," Manning said.

Manning feigned ignorance as to how he thought the Ravens would employ Dumervil.

Here's a hint, Peyton: He's coming right after you.

"We certainly know what a great athlete Elvis is, and what a playmaker he is," Manning said. "So he's certainly a factor we have to deal with."

To help offensive tackles Ryan Clady and Orlando Franklin deal with Dumervil, along with Terrell Suggs, Manning again asked the Broncos' home crowd for cooperation. At least once this preseason Manning flapped his arms while at the line of scrimmage to try to shush the crowd at Sports Authority Field at Mile High.

He asked them to save that noise for Joe Flacco and the Ravens offense Thursday.

"I want them as quiet as they can be when the Broncos are on offense," Manning said.
